IMPROVED REFRIGERATING-GHAMBER.

To ALL WHOM I'lv MAY CONCERN:

Be it known that I, JosEPuH'RAcEY, Jr., of the city, county, and State of New York, have invented. a new and useful Improvement in Refrigerating-Chambers; and I do hereby declare that the" following is a full, clear,-

and exact description of the same, reference being bad to the accompanying drawings, forming a part of this specification, in whic h- Figure 1 represents a plan of a refrigerating-chamber, constructed according to my improvement, as seen from. above, with the upper 'partofthe case removed. I

Figure 2, a vertical section of the same, in the plane indicatedby the'lin'e n; in fig. 1, and

Figure 3, a transverse sectional elevation through thc centre of the chamber, at right angles with fig. 2.

Similar letters of reference indicate corresponding parts in the sevcralfigures. v g

This invention relates to a novel arrangement of those parts of the interior of a refrigerat'or or refrigeratingchamber which contain the ice or refrigerating-substance or substances, whereby avcry large surface is obtained by a very simple construction, and provision is afi'orded for obtaining an effective ventilation of the refrigerator or chamber through which the foul or warm air ascends, and by whicha circulation is kept up, a ventilatin pipe being provided at the top'of'the structure for that purpose.

In order that others may be better enabled to understand the construction and operation of my improvement, Iwill proceed to describe it with reference to the drawings.

A is the box or case of the refrigerator; B, door to said case,fo r insertion or removal of such articles asit is designed to, preserve; E E are side boxes or receptacles, situated on cach'side, within the interior of the chamber, and secured to the upper .part of the case A by, a flange and screws, or other-suitable arrangement, intended to contain the refrigerating-substancc, which maybe plain ice, or ice and salt, or other refrigeratingmixture, and which is inserted through doors, FF, cut in the top of the case A. From these receptacles there project downwards, tonear thebott'om of said case, waved or corrugatedplatcs G G, united at the ends of the structure, and of a tapering or converging character, so as to be apart internally at'their upper ends,--where theyjoin the receptacles E E, but gradually approaching each other, andmeeting at their angular formation below, at which point the pockets H 'H, thus formed, estbblish an open junction withhorizontal receptacles or troughs I I. These pockets, throughout their entire depth, or nearly so, scrve,,with the receptacles E E, to hold the refrigerating-material, while the troughs I I contain the water produced by the melting of th e'latter, and which isallowcd to rim oifjhrough waste-pipes J J, which pass through the walls of the box or case A, and are slightly elevated for tlie purpose of regulating the level to which the water is allowed to collect. Thus the receptacle E, pockets H, and trough I,- being connected together in a water-tight manner, form one chamber, the tapering form of which prevents the ice, which is broken or ground to a given size, from settling too low therein, and the trough I, being fillcd with water from the melting ice, closes the discharge-aperture, and prevents any circulation-of air through the chamber containing the refrigerant, whilst the pipe K allows the escape of cool air or gases generated therein, into the body of the structure, which causes a circulation, and expels the warmer air through the inverted cone and ventilating-pipe a. Any number of these ice-chambers may be used, in proportion to the size of the chamber in' which they are placed, and converging, corrugated, or flutcdform, presents a more extended cooling-surface within the same space, and which increases iuan upward direction, where the air is naturally warmer.

What I claim as my invention, and desire to secure by Letters Patent, is r 1. The pockets H, constructed of a series of flutes or corrugations, connected in a tight manner at their upper ends with the chamber E, and at their lower ends with the trough I, said trough being providcd with a waste-pipe, J, and vent-pipe K, so arranged that the water from the melting ice shall accumulate in the trough, and prevent the circulation 0E- air through the refrigerant contained in said pockets, substantially as set forth. 2. The combination of the vent-pipe K with the inverted cone-vent a, arranged and operating essentially as shown and described.
